WIRE-CLOTH TO BE USED IN THE MANUFACTURE OF PAPER.

. SPECIFICATION forming part of Letters Patent No. 367,990, dated August 9, 1887.

Applica'tion filed September 24, 1883. Serial No. 107,271. (Specimens) Together the Edges of Wire Fabrics for use in the Manufacture of Paper, of which the following is a specification.

The object of myimproveinent is to provide a strong and efficient mode of whipping and joining together the ends or edges of wire fabrics of various constructions for use in Fourdrinier cylinders or other machines in the warp.

the manufacture of paper.

The accompanying drawings form a part ofthis specification. Said drawings are greatly enlarged, to show construction, and two styles or forms of construction as shown to which'my improvement is applicable.

Figure 1 is a view of a piece of wire-cloth, having the meshes between the pairs of double wires of the warp. These double wires are I two warp-wires close together, and are marked The filling b is single wire, and passes a1-' ternately over and under each wire in the warp. V

Fig. 2 is a view of apiece of wire cloth, the warp-wires of which are alternately one single wire, a, and one double wire, a. The meshes are between single and double wires'of The filling is all single wire, I), and passes alternately over and under each wire of the warp. There is also shown the end of wire-cloth whipped by the wire 0 and having three warp-wires between each two threads of the whipping-Wire c at the top.

Fig. 3 is a view of a piece of wire-cloth constructed the same as shown in Fig. 2. There are two warp-wires between each two stitches or threads of the whippingwvire c, and every alternate double warp-wire a is pricked apart, as at 6, through which opening the wire 0 is passed in whipping said edge or end.

Fig. at is a view of two pieces .of wire-cloth, like that in Fig. 2, the ends whipped substantially the same, the whipped ends or edges put together and joined together by the joiningwire f.

Fig. 5 is a view of two pieces of wire-cloth constructed like that in Fig. 3, the edges lhi whipped the same as in Fig. 3, the two whipped ends put together and joined by the joiningwiref.

Similar letters refer to similar parts in the several drawings.

. The construction of wire fabrics, as shown -in Figs. 1 and 2, and thejoining together the ends or edges thereof, is quite clearly described and shown in the explanations and drawings of said Figs. 1 and 2.

I will now describe my improved mode of whipping and joining together the edges or ends of wire fabrics, as hereinbefore indicated and as required for use in Fourdrinier or other machines in the manufacture of paper.

To whip the edges or ends of wire fabrics having therein alternate single and double warp-wires a and a, as shown in Fig. 2, take about the size wire used for warp in said cloth and use itfor a whipping-wire, 0. Then I preferably proceed as follows: Fasten the whipping-wire c to one selvage edge of the cloth, then pass it down to and around the first filling-wire or end of said cloth, then up to and over about the fifth filling-wire b, from said end, then down to and around said end, then up to and over the sixth filling-wire b, from said end, then down to and around said end, then up to and over the fifth filling-wire I), then down to and around said end, one stitch each, then up to and over the fourth fillingwire b, about three stitches, then, as before, down and around said end or first filliugwire and up to and over said fifth filling-wire, then to the sixth, then to the fifth, then to the fourth, each as before, and so alternate such stitching until the end is whipped, having three warp-wires between each two stitches or threads of said whippingwire c at the inner part of such stitching; or, if desired to have but two warp-wires between each two threads of the whipping-wire c, then every alternate double warp-wire a must be pricked apart, as at e, to admitthe whipping-wire c to pass through, as shown in Fig. 4.

To whip the edges or ends of wire fabrics having all of the warp double wires a, the meshes being between each pair of double wires to and a, as shown in Fig. 1, I prefer the whipping in'this case to be done the same or similar to that described for and shown in Fig. 2. If it is desired to have but two warpwires between each two stitches or threads of the whipping-wire c, then pass the whippingwire 0 through the meshes only. If it is desired to have three warp-wires between each two stitches or threads of the whipping-wire c,then prick open each alternate double wire a, to admit the whi ipiug-wire c to pass through. After the edges or ends of the wire fabric have been whipped, as hereinbefore stated, then to join the said edges or ends together I proceed as follows: Take about the size wire used for filling or whipping and use it for ajoiuing-wire, f. Then put the two whipped ends together, then fasten thejoining-wiref to one selvage edge, then pass said wire 1' continuously over or in rear of the first filling-wire and through the loops formed by the whippi ng-wires c at each of the two edges or ends of said fabric, and so continue from loop to loop until the joining is completed.

The joining-wire f should be drawn up tightly, so that the ends of theloops shall come snugly together. The joining-wiref may be fastened to the warp or filling of such fabric as and where desired, or as preferred by the operator.

I am aware that wire-cloth having the warp and filling all single wires has heretofore been made, the ends whipped and joined together by ajoining-wire, but such cloth whipping and joining did not contain the devices, process, or combination contained in and set forth in this my application. Therefore \Vhat I claim, and desire'to secure by Letters Patent, is-

l. The method of whipping and joining together the edges or ends of wire fabrics having double wi res i n the warp thereof, and which consists in fastening a whipping-wire to the edge of such fabric, then passing it down to and around the first fillingwire or the end of such fabric, then up to and around another filling'wire in the manner and where desired, then down to and around said end or first filling-wire, as before, and so continue until the end is whipped, changing the length of the stitches or loops as desired, so as to make the whipping smooth and strong, the double wires to be pricked apart where desired to admit the whipping-wire to pass through, then joining the two whipped ends together by means of ajoining-wire by passing it continuously over the first filling-wires of the two ends and through the loops formed by the said whipping-wires, substantially as and for the purposes described.

2. The method of uniting the edges of wire fabrics, consisting in forming loops around the first'and other transverse wires and then joining said loops by passing the connecting-wire through the adjacent ends of the loops in rear of the first transverse wires, substantially as described.

3. The method of uniting the edges of wire fabrics, which consists in passing a whippingthread alternately around the first transverse wire and then another transverse wire, alternating the length of the stitches, and uniting the two edges by passing a connecting-wire through the first wire loops of said edges and in rear of the first transverse wires, substan- JONATHAN B.
